One of those words with a complicated unfolding of senses. The origin is Latin *sequit-, past participle of seq- "follow", and the earliest meanings in English (late 1200s) are three senses of a "following":(i) attendance on a lord at court, i.e. following one's lord there;(ii) a lord's following, i.e. his company or retinue;(iii) the livery worn by a following or retinue.

Then came the sense of "pursuit", hunting or seeking, and in the early 1400s this developed the sense of pursuing someone at law, a lawsuit. This then widened to any supplication or petition (early to mid 1400s). In the late 1500s it took on the particular sense of "courtship, wooing".

Now I'm guessing it was the "livery" sense that around 1400 was extended to any set of matching things: first clothing; then playing-cards (early 1500s); and numerous obsolete uses. 'Suit of armour' is modern, no earlier than Sir Walter Scott.
